Hello, I'm using an esp32 built into a board that came from china. I'm having a huge problem because the port I need is connected to pins U0 (1,3). I wanted to be able to make the arduino IDE's serial monitor run on Serial2(16,17). I'm trying to use the SoftwareSerial library, with no success. I also tried to do it directly, unfortunately I had no evolution
U0, the ESP's programing port. Why not use one of the other 3 hardware serial ports on the ESP? I'd expect you'd not meet with success. Perhaps rewriting the ESP32 core or the programing port might be microcode or the OS boot rom.
Also, SoftwareSerial does not work well on a ESP32.
